Question 4

clinical signs of eimeria in lagomorphs

Answer 4

• Inappetence, Depression, Diarrhea, Dehydration, Weight loss, Fever, Anemia, Pale MM, Bad coat, pain
• Convulsions and paralysis in severe intestinal coccidiosis
• Death by dehydration and secondary bacterial infections
• Hepatic coccidosis: weakness, damage of liver & bile duct, coma

Question 5

Pathogenesis of eimeria in lagomorphs

Answer 5

• Highly contagious - causes enteritis, hepatitis, high mortality in youngs.
• Intestinal form leads to villous atrophy, and mucosal necrosis –> diarrhoea and poor absorption.
• Hepatic form (E. stiedae) invade bile duct –> hyperplasia, inflammation and bile duct obstruction. Leads to hepatomegaly, jaundice and ascites.

flotation

Question 7

treatment of eimeria in lagomorphs

Answer 7

diclazuril, toltrazuril, monesin, rodenidine

Question 8

Life cycle of Eimeria in lagomorphs

Answer 8

1) Exogenous sporogony - unsporulated oocysts are shed in feces of host, sporulation of oocysts happens in external environment
2) Endogenous merogony (asexual) - excystation of sporulated oocysts and 2-3 generations of merozoites
3) Endogenous gamotony (sexual) - production of microgametes and macrogametes that forms a zygote and is passed on with feces as unsporulated oocyst
